How to install TLK (Trusted Little Kernel)

Hi all,

Recently, I got interested in the ARM TrustZone technology. So, I’ve been figuring out some open source projects such as TLK for NVIDIA TK1 and Genode for FreeScale iMX53.
While installing TLK, I got stuck.

After building the TLK source code without a problem, I’ve attempted to flash the tos.img, an image file of the TLK.
However, nvflash shows an error message like the following,

taiji@taiji-Parallels-Virtual-Platform:~/source/Linux_for_Tegra/bootloader$ sudo ./nvflash --bl ./ardbeg/fastboot.bin --download …/…/tlk/build-t124/tos.img --go

According to this message, it seems to need a separate partition to store the TLK image.
However, there is no manual how I can solve this problem.
Is there anyone who knows how to handle this error?

My development board is the NVIDIA TK1 and the version of the Linux BSP is the R19.3.0.

Thanks in advance.

Looks like you are using fastboot. Fastboot requires the kernel going to a specific partition, and expects certain layouts…if you switch to u-boot you can just install normal L4T and then add a menu entry to extlinux.conf (in /boot) without that hassle. There’s no telling what size or alignment restrictions fastboot has.

FYI, u-boot is the default in R21.x, and there is no reason why you couldn’t have it run normally and place an alternate entry for boot from an SD card or SATA hard drive without disturbing the original install.
